Move unit test to the proper location

Summary: Move test/CodeGen/AArch64/reg-bank-128bit.mir to test/CodeGen/AArch64/GlobalISel/reg-bank-128bit.mir so that the test is executed only when global-isel is enabled. lit.local.cfg under test/CodeGen/AArch64/GlobalISel checks if 'global-isel' is in the available_features while the same file under test/CodeGen/AArch64 doesn't.
